چکیده مقاله:

The whole genome sequencing (WGS) of halophyte grass Aeluropus littoralis has generated valuable genomic resources to study the characteristics of gene families involved in various abiotic stresses such as salinity and drought stress. Calcineurin B-like proteins (CBLs) as a secondary messenger molecule belong to calcium sensors superfamily, which play a key role in regulating physiological processes, plant growth and development. In this study, the CBL gene family of Aeluropus littoralis and Arabidopsis Thaliana as two glycophytes and halophytes plant model were studied. Based on sequence homology and orthology/paralogy relationships with Arabidopsis genes, six CBL genes were identified in the Aeluropus genome, and were classified into three protein groups: AlCBL۴, AlCBL۲ and AlCBL۱۰. Protein domain analysis of the AlCBL gene family confirms the presence of four EF-hand domains in all of these genes, which provide a structure for calcium ion binding. The high similarity of the physicochemical properties of most Aeluropus proteins to Arabidopsis as well as the strong orthological relationship with each other may indicate the preservation of the function of these genes in the evolutionary process. Different expression profiles of AlCBLs in Aeluropus transcriptome also be an evidence for the functional divergent of these genes. The results obtained in this study can provide valuable information about the properties of this gene family and their functional roles for future studies
